            <ul>
                <li>Cancel &amp; save buttons are only enabled if the form is dirty — there is something to cancel or
                    save.
                </li>
                <li>Save button is only enabled if there are no validation errors on the form.</li>
                <li>Cancel reverts the form changes back to original state.</li>
                <li>Save updates the internal model of the form.</li>
                <li>Debug view shows the two models. One presented to the user form and the other being the pristine
                    copy master.
